| help |
| Some AMD SoCs support more than one PCI segment with 256 buses. Those |
| SoCs however have a different data fabric register layout for the PCI |
| bus number decoding. SoCs that use a data fabric register pair for |
| the PCI bus number which includes the segment number must select this |
| option; SoCs that use one data fabric register for the PCI bus number |
| which doesn't include a segment number field mustn't select this. |

| Some AMD SoCs support more than 48 bit MMIO addresses. In order to |
| have enough bits for this, the MMIO address extension register is |
| introduced. SoCs that have this register must select this option in |
| order for the MMIO regions to be reported correctly. |
